Definitions
- the invention relates to a method for profiling a multilayer fleece and a
- a profile forming device which is integrated in the card or card.
- the thickness or density of the pile profile emerging from the card is varied by a variable pile decrease on the card. This technology brakes the card and limits the working speed of the entire fiber system.
- the thickness or density changes of the pile are shown in Dependent on the respective position of the laying trolley on the non-woven layer and generated with a corresponding lead time, so that the non-woven layer then deposits them at the desired location on the take-off belt.
- the fleece thickness change and the fleece thickness profile are therefore generated and determined in front of the fleece layer.
- the invention solves this problem with the features in the main method and device claim.
- the profile-forming technique and the profile-forming device with the drafting device to be connected upstream of the nonwoven layer, preferably a stretching device, has the advantage that the pile thickness is influenced even before the pile is deposited
- Removal belt of the nonwoven layer takes place in a defined area and with improved and in particular more controllable influencing options.
- the card can run constantly and produce a pile with constant speed and constant thickness or density, which is favorable for the pile quality. In addition, very high working speeds of Reach 100 m / min and more.
- the pile fed directly or indirectly to the stretching device is only influenced in the stretching device and is preferably stretched in the process. This stretching and the associated thinning of the pile can be precisely controlled and influence the pile in a gentle manner.
- the thickness or density of the pile can be influenced within wide limits by means of a suitable design of the stretching device, so that there are very far-reaching control options for the thickness or density of the fleece running out from the nonwoven layer.
- the drafting device has the advantage that a precise definition of the drafting length can be created by at least two spaced-apart clamping points, within which the pile supplied is influenced and, in particular, stretched in the desired manner to form drafting. Warpage formation can be controlled better and more precisely by the defined warpage length. The pile delay can thus be controlled more precisely according to position and size in the pile. In this way, the different requirements of different pile types and pile thicknesses can also be taken into account.
- the size of the drafting length and in particular the stretching length can also be influenced and changed here by means of movable clamping points.
- Elastic piles which generally also have a larger pile thickness, are preferably treated with a short drafting or stretching length. This results in a plastic deformation of the pile, which is not canceled again after leaving the clamping points and the drafting device, but instead. remains in the pile at the desired location and with the desired strength.
- clamping rollers are used at the clamping points, which can be adjusted to the desired dimension on the pile and on a counter-roller or a conveyor belt or the like which is also driven.
- the clamping points can vary depending on the design of the fleece layer, the pile stretch or the pile generator, the clamping points can vary
- the stretching device consists of several roller arrangements, in particular pairs of stretching rollers, or several
- Conveyor belt sections with adjustable pinch rollers which pinch the pile between them and stretch them with continuous increases in speed.
- the speed level of the downstream fleece layer also changes, so that the pile is influenced primarily in the stretching device and the fleece layer takes over the pile from the stretching device essentially without any further pile change due to the speed adjustment.
- the stretching device is advantageously controlled via the pile path and depending on the position of the laying carriage.
- the pile path is always the same with a suitable design of the nonwoven layer between the entry point and the exit point on the laying car, because the changes in the way of the laying car are compensated for by corresponding changes in the way of the uppercarriage and the infeed conveyor or the belt loop between the upper and laying car. This results in a particularly simple and precise control option.
- product-specific changes in the laying width, the number of layers and the like can also be taken into account.
- the stretching device has the advantage that it can not only be attached to new fleece layers and can even be integrated in place of the previous feed belt.
- the stretching device can also be retrofitted to existing fleece layers without any problem and without increasing space requirements.
- the existing card or card can also continue to be used. Alternatively, it can also be assigned to pile producers or integrated into an overall system. It is not necessary to convert the entire nonwoven system as in EP-A-0 371 948 or WO 99/24650.
- the stretching device also requires little space and construction. It represents a particularly cost-effective, economical and, at the same time, highly efficient option for targeted nonwoven profile formation.
- the profile forming device can also be a
- a non-woven layer compensating device for the nonwoven which ensures a constant dispensing speed of the nonwoven to downstream machines, in particular a consolidation device, preferably a needle machine.
- a consolidation device preferably a needle machine.
- the compensation device can also be integrated into new fleece layers or retrofitted to existing fleece layers. It also requires only a small amount of construction and space. It can be controlled easily and precisely. It is also inexpensive and economical.
- the claimed profile forming device has the advantage that it can be used with existing fiber treatment systems without any problems together with a new fleece layer or an existing fleece layer. Neither the card nor the needle machine need to be adjusted or changed. These machines can be used as
- Standard components can be formed, which is particularly inexpensive and economical.
- the entire profile formation of the nonwoven takes place in the area of the nonwoven layer, but the nonwoven layer itself does not have to make any contribution to this and can also be designed as an inexpensive standard machine.

- profile changes can be made in the fleece area in between.
- the formation of a nonwoven profile can serve different purposes. On the one hand, it can be used to react to peculiarities of the consolidation device (4), in particular a needle machine. Needle machines usually have the peculiarity that due to the necessary warping, the fleece (9) jumps in over the width and this width shrinkage leads to thickening in the edge area, as a result of which the end product emerging from the needle machine (4) has an uneven thickness or density over the laying width Has. This is counteracted by the formation of the aforementioned fleece profile. In addition to these marginal effects, other inhomogeneities of the needle machine (4) or another consolidation device generated within the laying width can also be taken into account. Alternatively, through the

- the front nip (105) is variable in location along the conveyor path (120) and is formed by the nip roller (126, 127, 128) that is delivered in each case.
- the middle clamping roller (127) is advanced to its conveyor belt section (122) and forms the clamping point (105). The other two adjacent pinch rollers (126, 128) are lifted off and have no conveying contact with the pile (107).
- the drives of the pinch rollers (127) and the conveyor belt section (122) at the nip point (105) are coupled to the pile leading drives of the fleece layer (102) and are raised and lowered synchronously and uniformly in the level to produce the desired pile distortion.
- the conveyor belt section (121) closest in the pile conveying direction is also raised and lowered synchronously in the speed level in the same way.
- the third conveyor belt section (123) can also use the speed level of the fleece layer (102), alternatively, however, also the delivery speed of the pile collector (103) or the take-off rollers (118) or, in a further modification, a differential speed between the conveyor speeds at the clamping points ( 105,106) are driven.
- the delay device (104) of FIG. 8 can also be operated in other configurations and functions.
- FIGS. 9 and 10 show two of them ⁇ co c ⁇ o c ⁇ c ⁇
- the front pinch roller (126) and its conveyor belt section (121) in turn run faster than the middle pinch roller (127) and its conveyor belt section (122).
- the cascading speed levels are also determined by the common control (131) and their gradation is raised and lowered uniformly with the speed of the pile-driving drives of the fleece layer (102).
- the warping and in particular the pile stretching is canceled again as soon as the pile-leading drives of the fleece layer (102) and the synchronously coupled pinch rollers again run essentially at the delivery speed of the pile generator (103).
- the pile (107) is conveyed continuously and without warpage.
- FIGS. 11 to 15 show a third variant of the profile forming device 1 with modifications of the drafting or stretching device (5, 104) and the compensating device (6).
- the stretching device (5, 104) is integrated into the fleece layer and its housing at the inlet area (33) in a space-saving manner and takes the place of the previous inlet belt (15) of FIG. 1.
- the modified fleece layer (3, 102) has essentially the same width as a conventional machine and can therefore also be retrofitted and exchanged into an existing fiber treatment system (101) without major modifications.
- the stretching device (5, 104) can also be a retrofittable component with its own housing part. This can be retrofitted to an existing conventional fleece layer (3, 102), with its control (131) also being adapted, exchanged or with the ,
- Clamping rollers (126, 127, 128) are arranged on the machine frame of the stretching device (5, 104) above the deflection rollers (130) of the conveying sections (121, 122) lying at the front in the pile running direction (23).
- the third rear pinch roller (126) can optionally be dispensed with, which is shown by the broken line in FIG. 13. Alternatively, the middle pinch roller (127) can be omitted.
- the pinch rollers (126, 127, 128) are attached with their roller frame to vertical rows of holes in the machine frame and can thus be brought to the required height to the inclined conveyor belt sections (121, 122, 123).
- the clamping rollers (126, 127, 128) are mounted on their roller frames so that they can be adjusted in height by means of slides and can be adjusted using an infeed device (27), e.g. pull a cylinder vertically downwards against the pile (8, 107) or its associated conveyor belt sections (121, 122, 123) in the required manner and turn it on.
- the clamping point (106) facing the pile generator (2, 103) is formed by the first angled conveyor belt section (123) on the inlet side and its clamping roller (128). Both run essentially at the pile delivery speed.
- the second nip (105) is created in Figure 13 by the adjacent central conveyor section (122) and its nip roller (127). Both move faster or slower than that for profiling the pile (8, 107) or fleece (9, 107) in the manner described above
- the trigger tape (17, 116) is positioned accordingly. It can also run fully synchronized with the laying carriage (16, 111) and take part in its acceleration and braking phases.
- the moving average conveyor belt of the fleece feeder (22) is running, the fleece (9, 108) is temporarily jammed and forms the sag (32) shown in dashed lines in FIG. 15 in the gusset (31). If the speed of the discharge belt (17, 116) then drops again and falls below the mean value, the fleece feed (22) is faster and pulls the slack (32) flat again.
- Drafting device (5, 104) can, for example, work with other stretching or accumulating devices instead of the roller arrangements (11, 12, 13) or the conveyor belt sections (120, 121, 122, 123).
- the fleece (9, 108) can be applied to others in the compensation device (6)
- the compensating device (6) can be completely dispensed with if, for example, the consolidation device (4) is designed accordingly and with fluctuating ones
- Fleece feed speeds can work.
- other units, ' z. B. fleece plug-in units can be installed.
- the fleece (9, 108) can also be delivered from the fleece layer (3, 102) to a roller store or the like instead of the consolidation device (4).
